Cardiac Arrest
Conditions
Brief summary
Context: Chest compressions quality is known to be essential in cardiopulmonary resuscitation. Despite a known harmful effect of chest compressions interruptions, current guidelines still recommend provider switch every 2 minutes. Feedback impact on chest compressions quality preservation during cardiopulmonary resuscitation remains to be assessed. Study design: simulated prospective monocentric randomized crossover trial. Participants and methods: Sixty five professionals rescuers of the pre-hospital care unit of University Hospital of Caen (doctors, nurses and ambulance drivers) are enrolled to performed continuous chest compression on manikin (ResusciAnne®, Laerdal), twice, with and without a feedback device (CPRmeter®). Correct compression score (the main criterion) is defined by reached target of rate, depth and leaning at the same time (recorded continuously). Hypothesis: Feedback device preserve chest compression quality above the 2 minutes recommended switch over during cardiopulmonary resuscitation.

Intervention model description
In Guide group, participants have a real time feedback (and record) on chest compression quality performed by means of the visuals informations profided by the feedback device. In Blind group, participants have a real time record of chest compression quality performed by means of the feedback device without feedback information of the performance.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Correct compression score | Day 0 | Correct compression score is defined by reached target of rate (between 100/min and 120/min), depth (between 50 mm and 60 mm) and leaning (less than 2500g) at the same time |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Chest compression depth | Day 0 | Chest compression depth reached (in mm) |
| Chest compression rate | Day 0 | Chest compression rate per min |
| Percentage of chest compression without leaning | Day 0 | Percentage of chest compression without leaning defined with a residual weight egal or above 2500 g |
| Decrease time of 30% of correct compression score | Day 0 | Time at witch correct compression score decrease of 30% of the reference correct compression score (first 20 secondes) |
| Percentage of correct chest compression rate | Day 0 | Percentage chest compression rate between 100/min and 120/min |
| Participants' fatigue (Borg's scale) | Day 0 | Participant auto-evaluation of fatigue with a predefined scale from 6 to 20 (no unit). |
| Percentage of chest compression with correct depth | Day 0 | Percentage of chest compression with depth between 50 mm and 60 mm |
